This enforces `snake_case` for functions and methods only. Might be worth extending it to fields and locals too at some point in the future.
A number of breaking changes each detailed in the attached commits.
A number of functions/methods have been moved or renamed to align
better with rust standard conventions.

This patch makes `Arc::make_unique` examine the number of weak
references as well as strong references, which is required for safety.
It also adds a `make_unique` method to the `Rc` type for consistency.
Closes#14521.
Make check_for_assignment_to_restricted_or_frozen_location treat
mutation through an owning pointer the same way it treats mutation
through an &mut pointer, where mutability must be inherited from the
base path.
I also included GC pointers in this check, as that is what the
corresponding code in gather_loans/restrictions.rs does, but I don't
think there is a way to test this with the current language.
Fixes#14498.
We already have into_string(), but it was implemented in terms of
into_owned(). Flip it around and deprecate into_owned().
Remove a few spurious calls to .into_owned() that existed in libregex
and librustdoc.
This commit shuffles around some of the `rand` code, along with some
reorganization. The new state of the world is as follows:
* The librand crate now only depends on libcore. This interface is experimental.
* The standard library has a new module, `std::rand`. This interface will
eventually become stable.
Unfortunately, this entailed more of a breaking change than just shuffling some
names around. The following breaking changes were made to the rand library:
* Rng::gen_vec() was removed. This has been replaced with Rng::gen_iter() which
will return an infinite stream of random values. Previous behavior can be
regained with `rng.gen_iter().take(n).collect()`
* Rng::gen_ascii_str() was removed. This has been replaced with
Rng::gen_ascii_chars() which will return an infinite stream of random ascii
characters. Similarly to gen_iter(), previous behavior can be emulated with
`rng.gen_ascii_chars().take(n).collect()`
* {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all
relied on being able to use an OSRng for seeding, but this is no longer
available in librand (where these types are defined). To retain the same
functionality, these types now implement the `Rand` trait so they can be
generated with a random seed from another random number generator. This allows
the stdlib to use an OSRng to create seeded instances of these RNGs.
* Rand implementations for `Box<T>` and `@T` were removed. These seemed to be
pretty rare in the codebase, and it allows for libcore to not depend on
liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not
supported. If this is undesirable, librand can depend on liballoc and regain
these implementations.
* The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`,
but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice
structure now has a lifetime associated with it.

So far the DWARF information for enums was different for regular enums, univariant enums, Option-like enums, etc. Regular enums were encoded as unions of structs, while the other variants were encoded as bare structs. With the changes in this PR all enums are encoded as unions so that debuggers can reconstruct if something originally was a struct, a univariant enum, or an Option-like enum. For the latter case, information about the *Null* variant is encoded into the union field name. This information can then be used by the debugger to print a `None` value actually as `None` instead of `Some(0x0)`.
The changes in this PR should also fix the regression reported in #14385 and #14411, but I want to close these only after I have confirmation from the original reporters that the issues are actually fixed for them.
This patch makes `Arc::make_unique` examine the number of weak
references as well as strong references, which is required for safety.

This is a transitionary step towards completing #12517. This change modifies the
compiler to accept Partial{Ord,Eq} as deriving modes which will currently expand
to implementations of PartialOrd and PartialEq (synonyms for Eq/Ord).
After a snapshot, all of deriving(Eq, Ord) will be removed, and after a snapshot
of that, TotalEq/TotalOrd will be renamed to Eq/Ord.
According to the corresponding section, accessing a mutable static variable requires `unsafe` too, and I believe it counts as as language level feature. Add it to the relevant list in the Unsafety section.

rustc: clarify warning about native deps for a staticlib.
This adjusts the "unlinked native library" warning one receives when
compiling with `crate_type="staticlib"`. The warning is just trying to
tell the user that they need to link against these libraries, but the
old text wasn't making this obvious, the new text says this explicitly.
When spawning a process, stdio file descriptors can be configured to be ignored,
which basically means that they'll be closed. Currently this is done by
literally closing the file descriptors in the child, but this can have adverse
side effects if the child process then opens a new file descriptor, assigning it
to a stdio number.
To work around the problems of the child, this commit alters the process
spawning code to map stdio fds to /dev/null on unix (and a similar equivalent on
windows) when they are specified as being ignored. This should allow spawned
programs to have more expected behavior when opening new files.
